Here Is A Test On Penetrating Oils You WON"T Believe

[drizler]

Look at these numbers, it's just amazing......................... About the only thing I would watch out for is putting a torch on it under a car before the acetone has evaporated.. When I think of the busted knuckles I might have avoided in the last 30 years.......ughhhh Igor, you might want to tuck this away as a sticky for

The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!
